I had a female betta fish in a small tank. I had always keep her seperate tank becuse i have always heard the same thing about bettas. And that is to never keep them in the same tank. That they will tear each other to pieces and kill each other. But now i have been looking into it and i found an artical that said that you can put female bettas in the same tank with other fish and with other female bettas. So i put my female betta in my tank with my 6 tetras, 3 white clouds, and 1 cory cat. So far so good and the fish are not fighting with each other or any thing. But do you think that if i add platys (when i get the bigger tank set up) they will fight?
